Cog.

I meant to post this a few weeks ago, but of course, I forgot to do so...

This is a link to the Honda Accord "Cog" commercial. It's nothing less than amazing. One long continuous shot of the parts from a Honda Accord engaging in some sort of Rube Golbergian process, all on order to release a fully functional Honda Accord and an advertising banner.

No CGI.
One take.
Days to set it up.
I think they had 4 takes to get it right. The only time it worked, is the video that you are about to see.

Enjoy.
